Question

why tiny bubbles appeared of warter when boilng

Answer 1

When this occurs, they form gaseous molecules of water vapor, which float to the surface as bubbles and travel into the air. Instead of air, the bubbles in a boiling pot ofwater are actually made up of water — it's justwater in its gaseous state.

Answer 2

the air present in the water escapes while boiling water so we can see bubbles while boiling water
